When the engine unit 8 is at a maximum stroke, There is a small gap between it and the seat rail 21 . D. The air cleaner % is fixed to the transmission case 8b to accommodate a cleaner body 36a in which a filter (not shown) is housed, and a cleaner cover 36b is detachably mounted to the cleaner body One of the 36a is a left mating surface. A downwardly opening suction port 36c is formed on the cleaner cover 36b and a discharge port 36d is formed on one of the front walls of the cleaner body 36a. An intake port 37 is connected to the discharge port 36d. The intake pipe 37 is connected to a throttle body 38. As shown in FIG. 2, the rear wheel 7 is disposed on the center line of the body, such as a plane view. Show. The rear suspension 1 is configured to be positioned to the right of the body centerline c of the vehicle width direction (on one side of the rear wheel 7), the air cleaner 36 being configured to be positioned at the body centerline The left side of c (located on the other side of the rear wheel 7), and the throttle body 38 is disposed on the body center line c. Further, the rear suspension 10 is positioned on the rigid face of the air cleaner 36 to be disposed parallel to the throttle body 38 in the vehicle width direction. Furthermore, as shown in FIG. 1, when viewed from the side of a vehicle, the rear half 10 of the rear suspension 120625.doc -12-200819345 hanger is overlapped with the front portion of the air cleaner 36. 36', such that the front portion 36 and the rear half 1〇 form an overlapping portion. Further, a height position of the upper edge X of one of the rear slings 10 is substantially the same as the height position of the upper edge y of one of the air cleaners 36. According to the present embodiment, the rear suspension 1 is disposed on the right side of the vehicle width side of the wheel 7 after being positioned on the body center line C and the air cleaner 36 is disposed. On the left side of the vehicle width direction and above the transmission case 8b of the engine unit 8, the air cleaner 36 can be configured to effectively utilize the idle space provided above the transmission case 8b of the engine unit 8. Without hindering the rear suspension 1〇. Thereby, the air cleaner 36 can be sized to extend over substantially the entire length of the gearbox 8b of the engine unit 8, thereby increasing the volume. Furthermore, since the air cleaner 36 is disposed and fixed directly above the gearbox compensation and the rear suspension 10 is disposed on a side of the rear wheel 7 opposite to the transmission case 8b, It is easy to ensure a space in which the rear suspension 11 1G is disposed, and at the same time, the hoarding of the air cleaner 36 can be increased and, in turn, a larger diameter and longer rear suspension 10 can be used. In this embodiment, since the rear suspension 10 is configured to be substantially horizontally oriented in the longitudinal direction of the vehicle, and the rear suspension 10 is configured such that the rear half and the air cleaner 36 are in front of the vehicle The weight is 相, so that the rear suspension 1 配置 can be arranged along a line connecting one of the pivoting portions of the engine unit 8 and the rear wheel axle 17e, so that it can function The vertical load on the rear wheel 7 is converted into a longitudinal 120625.doc -13 - 200819345 load to effectively absorb the longitudinal load. According to this embodiment, since the rear suspension 1 is configured such that the height position of its upper edge X is substantially the same as the upper edge y of the air cleaner 36, the rear suspension 10 can be disposed at One of the lower positions of the body frame 2 lowers the position of the seat 9 in the height direction to enhance the quality of the foot's ground. • According to the present embodiment, since the accommodating portion 33c is disposed between the rear rear seat 10 and the rear suspension 10 which is positioned higher than the main seat 9a, The increase in the volume of the accommodation is utilized to effectively utilize the space generated between the rear suspension 1 〇 and the longitudinal rear seat 9 b by horizontally arranging the rear suspension 10, so that a helmet such as a helmet can be accommodated. Larger object. Further, since the longitudinal rear seat 9b is positioned at a position higher than the main seat%, the quality of the foot on the ground can be ensured, and the rear accommodating portion 33c can be made larger in size.
